CUTTERBAR
Continued.
How to sharpen and balance the cutterbar: A slightly
worn cutterbar may be re-sharpened. Both cutting edges
must be sharpened equally to ensure balance. Sharpen the
cutterbar every 25 mowing hours or more frequently if con-
ditions require. Remove the cutterbar from the mower and
30 -45
clean using a brush and water. Inspect the cutterbar for
signs of damage.

WARNING - PREVENT ACCIDENTS : DO NOT use a
damaged or excessively worn cutterbar.
Sharpen both cutting edges with a flat file to restore the
original cutting edge.

Ensure that the cutterbar is balanced. Use a screw driver
with a round shaft to support the cutterbar through its centre
hole. Hold the cutterbar horizontal and then release. A bal-
anced cutterbar will remain horizontal. If the cutterbar is
not balanced the heavy end will rotate downwards. Sharpen
the heavy end until the cutterbar is correctly balanced.
